Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593852, here are decompositions:

13 + 31593839 = 31593852
19 + 31593833 = 31593852
89 + 31593763 = 31593852
131 + 31593721 = 31593852
149 + 31593703 = 31593852
163 + 31593689 = 31593852
211 + 31593641 = 31593852
223 + 31593629 = 31593852

Showing the first eight; more decompositions exist.
